asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.

keep f32 in SSE registers and f64 in x87.  This

should never be needed and it appears to be true.
(It if is needed, adjustment would be needed for
long double to work.)

GCC optimizes away things like ptr < NULL  to false.  To "fix" this,
have the CBE emit casts of pointers to intptr_t when doing relational
pointer comparisons.

double from some of the many places in the optimizers

Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.

Similar to #1 except this is used for def : Pat patterns.
